Paraskeletal and extramedullary plasmacytomas in multiple myeloma at diagnosis and at first relapse: 50-years of experience from an academic institution.

ABSTRACT: From January 1970 to December 2018, 1304 patients were diagnosed with multiple myeloma (MM) at our institution and 256 (19.6%) had plasmacytomas (Ps) (paraskeletal -PPs- 17.6%, extramedullary -EMPs-1.9%). Patients with Ps had lower serum M-protein and less advanced ISS stage than those without. At first relapse, 192 out of 967 patients (19.8%) developed Ps (PPs 14.6%, EMPs 5.1%). The only factor associated with Ps at relapse was the presence of Ps at diagnosis (46% vs 13%, p < 0.00001) with no impact with exposure to novel drugs or previous autologous stem-cell transplantation (ASCT). The median overall survival (OS) was 45, 44 and 20 months for patients without Ps, PPs and EMPs, respectively (p = 0.013). Patients with PPs who underwent ASCT had similar OS than those without Ps (98 vs. 113 months) and significantly longer than those with EMPs (98 vs 47 months, p = 0.006). In patients non-eligible for ASCT the presence of PPs or EMPs was associated with shorter OS compared with patients without Ps (32 vs. 24 vs. 6 months, p = 0.009). In the relapsed setting, a significant survival benefit was observed beyond the year 2000, but still with significant differences among patients without Ps, PPs and EMPs (37 vs 22 vs 16 months, p = 0.003). Importantly, rescue therapy with combinations of proteasome-inhibitors plus immunomodulatory drugs was associated with prolonged OS from first relapse (over 6 years), even in patients with EMPs.

Project description:IntroductionExtramedullary plasmacytoma (EMP) is an uncommon solitary tumor originating from neoplastic plasma cells located outside the bone marrow. Despite its rarity, the occurrence of EMP without a concurrent diagnosis of multiple myeloma (MM) is considered extremely rare. Approximately 80-90% of EMP cases are found in the head and neck region, with a higher incidence in men aged between 50 and 60 years. The current treatment modalities include radiotherapy (RT) as a first-line approach, with surgery or chemotherapy regarded as other therapeutic options. While RT proves effective in the majority of EMP cases, there are instances where the tumor remains refractory to radiation. In this case report, we present an unusual scenario of EMP resistant to RT without concurrent signs of multiple myeloma which was successfully treated with surgery followed by systemic therapy.Case reportA 72-year-old male was admitted to the Head and Neck Cancer Clinic with a 6-month history of swallowing difficulties. He denied experiencing weight loss or pain on swallowing. Basic laboratory tests yielded results within normal limits, except for beta-2 microglobulin. Physical examination revealed an enlarged submandibular lymph node on the right side. Fiberoptic examination identified a soft tissue polypoid mass within the right piriform fossa, slightly protruding into the vocal slit. A CT scan displayed a well-circumscribed 2 cm polypoid, homogeneously enhancing soft tissue mass adjacent to the posterior surface of the epiglottis and the right side of the tongue base. Bone marrow biopsy revealed no abnormalities, and there were no clinical or laboratory signs of multiple myeloma. Based on the tumor biopsy results and imaging studies, a diagnosis of EMP was made. Due to the lack of response to RT, surgical removal of the tumor was pursued, followed by systemic therapy. Ultimately, the patient achieved full recovery with effective disease control.ConclusionIn conclusion, EMP without concurrent multiple myeloma is an exceedingly rare condition that demands a multidisciplinary approach for both diagnosis and treatment. Moreover, although RT continues to be the primary standard treatment for EMP, in some cases other therapeutic regimens prove to be successful.

Project description:BackgroundBladder cancer is known to be strongly associated with smoking tobacco products. Urologists thus have an imperative role in providing smoking cessation counseling to patients to prevent the development of bladder cancer, recurrence, and other morbidities associated with smoking. Asymptomatic hematuria is often a presenting clinical symptom that warrants further investigation. This study aims to determine if smokers who have an episode of asymptomatic hematuria are more likely to quit smoking if urologists counsel them on formal smoking cessation.MethodsWe completed a retrospective chart review of patients who presented for asymptomatic hematuria at our institution between January 2017 and March 2020. A total of 435 patients were identified, 134 of which were active smokers at the presentation time. We recorded smoking status at initial presentation, documentation of smoking cessation counseling, and smoking status at one year follow-up. Fischer's exact test was used for analysis. Statistical significance was set by convention at P<0.05.ResultsThe percentage of patients presenting with an episode of asymptomatic hematuria that quit or cut back at one year follow-up was 24.2% [95% confidence interval (CI): 13.8%, 34.7%]. In assessing the effect of formal smoking cessation counseling, 33.3% of patients with documented smoking cessation counseling quit or cut back at one year, compared to 22.8% of patients with no documented counseling. However, these findings were not statistically significant (P=0.68). Of note, smoking cessation counseling was recorded in 19 active smokers (14.2%), and 68 active smokers (50.7%) did not receive follow-up at one year.ConclusionsSmoking cessation remains a challenging endeavor for both patients and urologists. Formal counseling did not significantly contribute to quitting rates among patients, and rates of documented counseling from providers were unsubstantial. Urologists should use hematuria work-up visits as an opportunity to counsel patients on smoking cessation.
